I'm implementing a deployment/rollback procedure using Jenkins 1.430. I would like to configure the deployment and the rollback steps as 2 separate jobs so as to be triggered independently if needed. However I would also like the rollback to be triggered automatically when the deployment fails.

When I go to the Post-build Actions configuration section of the deployment job, I can choose to Build other projects. If I check that setting I get 3 options:-Trigger only if build succeeds
-Trigger even if the build is unstable
-Trigger even if the build fails
